Diagnostic LEDs
Tag Description
SS
The SS LED will light if the unit is not getting a response
from one or more of the configured devices.
ERR
The SYS ERR LED will go on solid indicating there is
a system error. If this occurs, immediately report the
related “system error” shown in the error screen of the
FS-GUI interface to support for evaluation.
PWR
This is the power light and should always show steady
green when the unit is powered.
TX
The TX LED will flash when a message is received on
the serial port on the 3-pin connector.
If the serial port is not used, this LED is non-
operational
. TX1 applies to the R1 connection while
TX2 applies to the R2 connection.
RX
The RX LED will flash when a message is sent on the
serial port on the 3-pin connector.
If the serial port is not used, this LED is non-
operational
. RX1 applies to the R1 connection while
RX2 applies to the R2 connection.

Appendix A.5 Taking a FieldServer
Diagnostic Capture
When there is a problem on-site that cannot easily be resolved,
perform a diagnostic capture before contacting support so that
support can quickly solve the problem. There are two methods for
taking diagnostic captures:
●
FieldServer Toolbox:
This method requires installation of the FS Toolbox program. A
FS Toolbox diagnostic capture takes a snapshot of the loaded
configuration files and a log of all the communications on the
serial ports over a specified period of time. If the problem occurs
over an Ethernet connection, then take a Wire Shark capture.
●
Gateway’s FS-GUI Page:
This method doesn’t require downloading software. The
diagnostic capture utilities are embedded in the FS-GUI web
interface. Starting a diagnostic capture takes a snapshot of the
loaded configuration files and a log of all the communications
over a specified period of time. This works for both serial and
Ethernet connections.
Note
The information in the zipped files contains everything
support needs to quickly resolve problems that occur
on-site.
